Pruning Overgrown Bougainvillea (Bogenvia) in San Diego

Renovating a 10-Year Neglected Bougainvillea

Never remove >⅓ of the plant in one season—shock risk. Since it's not blooming well, pruning is overdue.

When & How

• Timing: After bloom drop (fall) or late winter (mid-March ideal).
• Method: Remove ⅓ of oldest stems to base. Thin crossing/dead wood. Shape for air flow.
• Tools: Sharp bypass pruners; loppers for thick stems.
